Overuse of artificial chemical fertilizers could be detrimental to the environment. Utilizing beneficial microorganisms as biofertilizers is a sustainable technique that promotes soil health, crop yield, and ecosystem preservation. L. is utilized as a medication since it has its antibacterial, anti-microbial, and anti-tumor characteristics, which reduce inflammation and hasten wound healing. The effect of strain MSR1, which is common in the roots of alfalfa grown in the Al-Ahsaa region, on plants is being investigated. rhizomes were planted under greenhouse conditions after being submerged in a solution of strain MSR1 (OD 500) or water treatment as a control for 12 hours. After 240 days of growing, ten randomly selected plants from each treatment were collected, and the vegetative growth and yield metrics were assessed. To investigate how influences production and chemical composition (photosynthetic pigment, nitrogen, phosphorus, potassium, and curcuminoid), measurements were conducted as well as genes diketide-CoA and curcumin synthases genes. Our research showed that growth and yield were favorably impacted by Significant increases in the related plants' chlorophyll a,b, carotenoid, nitrogen, phosphorus, and potassium levels were likewise a reflection of the enhanced effects shown in the growth and yield parameters. Treatment with raised the curcuminoid's three sub-components' compositions to varying degrees: bisdemethoxycurcumin, demethoxycurcumin, and curcumin. Comparing treated plants to the control, high expression levels of the genes diketide-CoA and curcumin synthase-1, -2, and 3 were also found. The treatment of is a good biostimulant candidate for boosting growth and yield as well as raising the medicinal qualities of C. longa, according to the overall results.
过度使用人工化学肥料可能对环境有害。利用有益微生物作为生物肥料是一种可持续技术，可促进土壤健康、作物产量和生态系统保护。由于L.具有抗菌、抗微生物和抗肿瘤特性，可减轻炎症并加速伤口愈合，因此被用作药物。正在研究在Al-Ahsaa地区种植的苜蓿根中常见的MSR1菌株对植物的影响。将根茎在MSR1菌株溶液（OD 500）或水处理（作为对照）中浸泡12小时后，在温室条件下种植。生长240天后，从每个处理中随机选取10株植物，评估其营养生长和产量指标。为了研究其如何影响产量和化学成分（光合色素、氮、磷、钾和姜黄素类化合物），还进行了测量以及二酮基-CoA基因和姜黄素合酶基因的检测。我们的研究表明，其对生长和产量有积极影响。相关植物的叶绿素a、b、类胡萝卜素、氮、磷和钾水平的显著增加同样反映了生长和产量参数中显示的增强效果。用其处理不同程度地提高了姜黄素类化合物的三个子成分的含量：双去甲氧基姜黄素、去甲氧基姜黄素和姜黄素。与对照相比，在经处理的植物中还发现了二酮基-CoA基因和姜黄素合酶-1、-2和-3的高表达水平。总体结果表明，其处理是促进生长和产量以及提高长柄姜药用品质的良好生物刺激剂候选物。
